CHEMICAL EQUATIONS
A chemical equation describes what happens in a chemical reaction. The equation identifies the reactants (starting materials) and products (resulting substance), the formulas of the participants, the phases of the participants (solid, liquid, gas), and the amount of each substance, given by the coefficient, which is the number in front of the formulas or symbols and it means the amount of moles of substance (number one is understood).
Example:
Reaction: 4Na(s) + O2(g) → 2Na2O(s)
Reactants: 4Na(s) + O2(g)
Products: 2Na2O(s)
Formulas and symbols: Na, O2, Na2O
Phases: (g), (s), (l), (aq)
Coefficients: 4 + 1 2
HOW TO READ A CHEMICAL REACTION
For the example above we will read: 4 moles of Sodium in solid state are reacting with 1 mole of Oxygen gas to yield 2 moles of Sodium Oxide solid. BALANCING CHEMICAL EQUATIONS TYPES OF CHEMICAL REACTION ENERGY OF CHEMICAL REACTIONS
